Why is LFU necessary?
LFU is essential for people who experience breathing difficulties, chronic cough or other related symptoms. This test is also important for those already diagnosed with lung diseases such as asthma, chronic obstructive pulmonary disease (COPD) or fibrosis, to monitor disease progression and the effect of treatment.
How do I prepare for LFU?
An LFU requires minimal preparation on your part. You should avoid heavy meals two hours before the test and refrain from smoking at least one hour before. If you are taking medication, it is important to inform your doctor as some medications can affect test results.
How is lung function testing done?
During LFU, you will be asked to breathe in and out through a mouthpiece connected to a spirometer. The spirometer measures the volume and speed of the air you inhale and exhale. The test can vary, but generally takes around 15 to 30 minutes.
What do the results mean?
Your LFU results will provide a detailed analysis of your lung function. The doctor will examine the results and compare them to normal values based on your age, height, gender and ethnicity. Abnormal results can indicate the presence or progression of a lung disease.
What happens after LFU?
After the test, your doctor will review the results with you and discuss any necessary steps. Depending on your results, you may need further investigations, medical treatment, or advice on lifestyle changes to better manage your lung health.
